'lo all whom it may concern:

Be it known that I, "f1-:reinas C. BALL, of Keene, in the county ofCheshire and State or New Hampshire, have invented a nen7 and usefulDevice for Rocking Cradles; and l do hereby declare that the followingis a full and exact description of the saine, reference being inade tothe annexed drawing, which is a perspective view.

The nature of this invention consists in having pieces, which are Workedby cranks driven by l`springs, or other equivalent inechanisin, arrangedto litt alternately on opposite sides ot a cradle, with sul'licienttorce to cause it to rock, er when it is set to rocking, to maintain thenionientuni and keep it in motion. lt is constructed in the ollov'- ingmanner:

represents a portion et a cradle, to which this is attached.

B is a frame Werk for the Workingparts. The spring and gearing; foroperating` the cranks is incased therein, and is not shown in thedrawing as such inechanisin is Well known.

C, C, are the cranks which work the pieces D, D,-their crank pins 'areset at opposite points, so that D, D, strike alternately on the iioor orsurface on which the cradle rocks, and litt on its opposite sides, toassist in reversing its niotion and to give an inipetus, suliicienttoovercoine its tendency to rest. D, D, are guided by the slot E, anderossbar F.

G is a key t'or Winding up the spring, which coils around the shaftlL-there is a toothed-Wheel on the shaft H, Which is connected to it bya ratchet and paivl, and receives inotion thereby as the spring` un-Winds, it nieshes with a sinall pinion on shaft which has another largewheel that Works in pinions on the shafts or the cranks C, C, andtransmits the inotion to theni. T he niotion of the cranks as the cradlerocks, acts an escapenient to regulate the un- Winding` of the spring.

Tc putit in operation, the spring, is Wound up, by turning the key Gr,and the cradle being set in motion, the cranks C, C, and pieces D, D,operate in the inanner described to keep the cradle rocking, until thespring' is run down, Without requiring the attention of a` person.

`What claim as iny invention, and desire to secure by Letters Patent,is,
